Leners Patent Ne. 110,333, dated Deeember 2o, 1870.

IMPROVEMENT IN COMBINED LAND-ROLLERS AND MARKERS.

The Schedule referred to in these Letters Patent and making part o! thesame.

To all whom it may concern;

Be it known that I, HENRY F. BAKER, of Centreville, in the county ot\Vayne and State of Indiana, have invented a new and valuableImprovement in Combined Land-Roller and Marker; and I do hereby declarethat the following is afull, clear, and exact ldescription of theconstruct-ion and operation ot' the same, reference being had to theannexed drawing making a part of this specication and to the letters andfigures of reference marked thereon.

Figure l of the drawing is a representation ofmy eld-roller in planview, and

Figure 2 is a transverse vertical section ot' the same.

The nature of my invention consists in the construction and arrangementof a field-roller 'combined with suitable device for laying oil` theground both ways.

In order to enable others skilled in the art to which my inventionappertaius to make and use the same, I will new proceed to describe itsconstruction and operation.

A represents the frame of my machine, iliade of any suitable dimensions,and having the roller B' mounted within the same.

In the center of the roller B, directly opposite each other, are placedtwo shovels or shares, a a, and on each side otl both of these shovelsis a sliding bar, b, inserted in the roller.

These bars l1 b can be adjusted at any desired point to or from thecenter of the roller by nieans of the screws e e, and to each of saidbars is another shovelY a lever, C, which extends forward across theroller -near the center, and is supported above the same on a standard,D.

On the under side of this lever is a pin, f, which, by the letting downof the lever, is made to enter holes in the roller B, for a purpose thatwill be presently described..

,In the front part of the frame is an'adj nstable bar, E, extendingbeyond both sides of the frame, and provided at its ends with rods l;le'.

On one end ot' the roller B are two pins, i i, which, as lthe rollerrevolves, raise a spring, la, attached to the frame.

This spring is for the purposeof giving notice that the shovels orshares are properly in the ground,

that the driver may see that the indicator points to the check-hill infront of the roller.

If the roller has gained or lost, the driver will pull down the lever Gso that the pin f will enter one of thevholes near the center of theroller, which will stop the roller from revolving until the indicatorpoints to the proper hill.

Having thus fully described my invention,

lVllat I claim as new, and desire tosecure `by Letters Patent, is

l. The sliding bars b Ib, provided with shovels a a', and adjusted atany desired distance from the center in the roller B, substantially asand for the purposes herein set forth.

2. 'lhe roller B, provided with stationary shovels a a and adj nstableshovels a a', substantially as and for the purposes herein set forth.

3. In combination with the roller B, constructed as described,the leverC with pin f, substantially for the purposes herein set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

HENRY F. BAKER.
